Struct CustomCursorImage 

pub struct CustomCursorImage {
    pub rgba: Arc<[u8]>,
    pub size: [u16; 2],
    pub hotspot: [u16; 2],
}

A bitmap cursor pushed to the integration via PlatformOutput::cursor_image.

The integration is expected to upload this to the OS as a real cursor (so the image is not clipped by the egui window — what egui::Painter drawn cursors suffer from). Backends that don’t support it should fall back to PlatformOutput::cursor_icon.

rgba is straight (non-premultiplied) RGBA — same encoding as winit::window::CustomCursor::from_rgba. The buffer length must be exactly size[0] * size[1] * 4 bytes. size and hotspot use u16 to match winit’s native types and avoid a lossy cast in the integration layer.

Arc<[u8]> is used so integrations can dedupe / cache by pointer identity (Arc::ptr_eq) and avoid re-uploading the same bitmap to the OS every frame.
